2007-03-11[SCSI] lpfc: avoid double-free during PCI error failureLinas Vepstas
If a PCI error is detected that cannot be recovered from, there will be a double call of lpfc_pci_remove_one(), with the second call resulting in a null-pointer dereference. The first call occurs in lpfc_io_error_detected(), and the second call during pci device remove. This patch eliminates the first call; its un-needed.

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells
Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

2006-08-19[SCSI] lpfc 8.1.9 : Stall eh handlers if resetting while rport blockedJames Smart
Stall error handler if attempting resets/aborts while an rport is blocked. This avoids device offline scenarios due to errors in the error handler. Background: Although the transport is using the scsi_timed_out functionality to restart the timeout if the rport is blocked, if the timeout has already fired before the block occurs, the eh handler still runs and can take the device offline. Ultimately, this window cannot be resolved without significant work in the error handler thread. Christoph noted the first level of these issues when he noted the poor error response handling by the error thread. We found, under heavy load and error testing, that time window from when the scsi_times_out() adds the io to the queue to when the scsi_error_handler gets around to servicing it, can be in the several seconds range. In most cases, these test conditions are highly unusual, but possible. As a result, we're stalling the error handler in this race window so that we can avoid the device_offline transitions.
